If you're searching for natural sound and modern design, the Spirit series is the perfect choice. Due to the custom designed Drive Units which were developed for this series, the loudspeakers play with the highest fidelity. In the mid and high frequencies, the speakers are capable of a high dynamic range as well as a very natural sound by virtue of the ornate crossover filter and the waveguide technology. The bass drivers have a long linear excursion, to ensure deep and articulate bass reproduction for optimal listening pleasure. The cabinets feature multiple internal bracing to achieve a non resonant cabinet. To showcase the quality of the Spirit series, the cabinets are painted with a perfectly finished multi-layer paint which make the speakers aesthetically appealing in a domestic environment.
